SHEET-METAL CAIN.

SPECIFICATION forming part of Letters Patent No. 298,801, dated May 20,1884.

Application filed June 18, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS A. WALsrr, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Sheet -Metal Cans; and I hereby declare the following to be a full,clear, which will enable others skilled. in the art to which myinvention relates to make and use the same, ref erence being had to theaccompanying drawings, forming a part thereof, and in which the fourfigures represent a sectional elevation of one corner of a sheet-metalcan, constructed as hereinafter more fully explained in detail.

The object of this invention is to construct a can in which the covermay be securely united to the can and removed therefrom without injuryto the can, so that it may be used rep eatcdly for the same purpose, andin which the cover may be cut away and a slip-cover applied; or the canmay be opened by removing the fastening device, in which latter case thecover may be used as a temporary or air COVGI.

In the drawings, a represents the body of a sheet-metal can, and Z) itscountersunk cover or end, provided with a wall, 2', which fits closelywithin the end 0 of the can body,

shown in this case to be formed of a separate piece united thereto, andpreferably such end is made seamless, as described in anotherapplication pending with this, so that the wall i may fit tightly withinthe collar or end 0. Said collar may be formed and united to thecan-body as shown in Figs. 1 and 2, and

the can-body proper, and an external one, for the burr 0, or so thatboth of said shoulders lie beyond the circumference of the body, as seenin Figs. 3 and 4.

I11 Fig. 1 the wall/t ot the cover I) is made high enough, so that itmay be turned outward and down against the outside of the collar c andunder the exterior shoulder, 9, forming a part, 2, having a burr, 0,which holds the cover securely to the end of the can. Said cover mayreadily be removed by running a suitable tool under the burr o tostraighten it out, or it may be cut away, so as to allow the cover to belifted up.

In Fig. 2 the wall '11 is made of the same height as the collar 0, andthe cover bis securely united to the can by means of a separate annularpart, i, provided with a flange, d, of which part i the inner wall ismade high enough to turn over and down against the collar 0 and underthe exterior shoulder 9, so as to form a burr, 0, which will hold thecover in its place and without in any way changing or injuring the formof the can-body, and which may therefore be removed, as before stated;or the cover may be cut away inside of the fiange d or shoulder g and aslipcover, 8, applied, fitting either over the inside or outside of thepart A packing, m, is also shown 011 top of the collar 0 in Fig. 1, orover the collar 0 and flange z" in Fig. 2, made of rubber, white lead,or similar mate rial,to make the can air-tight. The shoulder g-that isto say, the portion of the collar 0 on which the cover rests in Figs. 1and 2 and the packing m rests in Figs. 3 and 4forms a rest or support tothe cover while the can is being closed,or for the intermediate packing,and also strengthens the canagainst lateral compression.

In Figs. 3 and 4 the collar 0 is provided with an exteriorundershoulder, g, and is soldered to the outside of the can-body at such aheight as to leave a rim, f, projecting up beyond said shoulder, andthereby a space or channel is formed,into which is laid a rubber orother packing, m, upon which the cover I) rests and is supported on theshoulder g in Figs. 1 and 2.

In Fig. 3 the upper end of the wall z" is formed into a bead, r, whichstiffens the wall 1', and also gives a firm hold to remove the cover,which in this construction acts as a cork.

In Fig. 4 the wall i and collar 0 are of the same height, and aresecured by the separate part i, made without the flange d, which securesthe cover by the burr 0, turned under the shoulder g. In this case thepacking m is under the cover b. The part i secures the cover to thecollar c,and may be in one piece with the covcr,as shown inFig. 1, or itmaybe a separate part, as shown in Figs. 2 and 4, and in either casewith the seamless collar 0 it forms atight and strong closure. The partc may also be made a part of the cover 1), shown in Fig. 3, in which theupper part forms a ring, Z.

What I claim is- 1. A can provided with a collar, 0, having a shoulder,g and g, and with a cover, I), united to said can by a part, i,whereofthe part projecting beyond the collar 0 is turned over outward and downagainst the collar 0 and under 10 the shoulder g, substantially asspecified.-

' 2. A can provided with a shoulder, 9, packing an, and cover I), unitedtogether by a separate part, i, substantially as specified.
